きた。 Selection of Element Generally, when other elements are added to copper, the secondary elasticity (Young's modulus) tends to decrease, but when nickel is added, the Young's modulus is improved. Copper, nickel, silicon, iron, titanium, and boron alloys are for the purpose of forming an intermetallic compound and having high strength, heat resistance, and high-strength conductivity. This alloy property changes greatly depending on the amounts of nickel, silicon, iron and titanium. This alloy can maintain its strength even when continuously heated to a high temperature. Excellent heat resistance. Age-hardening special copper alloy is copper, nickel,
An alloy of iron, silicon, titanium, and boron is an intermetallic compound or a solid solution having the intermetallic compound as a matrix, which is a main factor for hardening. The quenching temperature is 850 degrees Celsius and the tempering temperature is 400 degrees Celsius for 2 hours.
It age-hardens at 450 degrees in 1 hour. In this way, the age-hardening special copper alloy made by repeating the experiment could be composed.

ものである。 Addition Ratio of Elements The age-hardenable special copper alloy of the present invention has a bad effect on the workability of the alloy when the content of nickel exceeds 5% by weight. Further, since the corrosion resistance deteriorates with a small addition amount of 0.1% or less, the addition amount is within the range of 0.1 to 5%. In order to provide the desired strength and ductility of the age hardening special copper alloy, it is desirable to add it in the range of 1 to 2.5%. Addition of silicon in an amount of 7% or more deteriorates workability and deteriorates mechanical properties and electrical conductivity. Further, if it is less than 0.01%, there is no effect.
It is preferably added at 0.1 to 2.5 percent. When iron is added in an amount of 10% or more, the electric conductivity and the corrosion resistance deteriorate. In addition, addition of 0.01% or less has no effect. It is preferably added at 1 to 5 percent. When titanium is added in an amount of 7% or more, the workability deteriorates and the electrical conductivity deteriorates. Further, if it is less than 0.01%, there is no effect. It is desirable to add at 0.1 to 2.5 percent. Boron contributes to corrosion resistance and hardness. It is also very effective as a deoxidizing agent for age-hardening special copper alloys. Addition of 1% or more adversely affects the workability. A small amount of 0.1% or less is preferable. It is preferable to add 0.002 percent. The above remaining amount is copper and is an age hardening special copper alloy.
